2. Introduction

The automatic train control relay extends the signal control modules by adding the possibility to stop the
train. It interrupts the traction current (separate for track and / or catenary) of a "stop" signal by bipolar
changeover switches. In digital use, it can control the brake module, item 5232 (MM) or a brake generator
for DCC.
2.1 Electronic relay
Independent from the signal modules, module item 5228 is also suitable for various other switching tasks.
The three pin contacts on the left hand side serve as control input. Cables can be connected with sockets
(items 6879 – 6887). The circuit diagram is printed onto the module. Fig. 1 is a schematic layout of the

connection.

3. Connection
Connect the automatic train control relay to the module as shown in the following figures. The contact pins fit
into the plugs of the signal modules. This creates the electrical connection and keeps the relay mechanically
connected to the module.
